A/G Ratio (Albumin/Globulin Ratio)

The A/G ratio is a calculated value comparing the amount of Albumin to Globulins (Total Protein minus Albumin). In the Proteins & A/G Ratio panel, it serves as a sensitive indicator of liver and kidney health as well as nutritional status and plasma cell disorders. A shift in this ratio often precedes clinical symptoms of systemic disease.
Why Context Matters
A high ratio is frequently just a sign of dehydration rather than disease. Conversely, a low ratio requires careful follow-up with Protein Electrophoresis to rule out monoclonal gammopathies like Multiple Myeloma.
Lab ranges are statistical averages, not biological laws. "Normal" for a 20-year-old male isn't normal for a 60-year-old female.
